Question

Why are sound waves called mechanical waves?​

Answer 1

Answer:

Mechanical wave- Waves that require a medium ( solid, liquid or gas) to travel are known as mechanical waves. ... So, sound waves are longitudinal. Also, it cannot travel through a vacuum and requires a medium (solid, liquid, or gas) to travel. Thus, a sound wave is called a mechanical wave.

Answer 2

Answer:

A sound wave is a wave in which particles vibrate in the direction parallel to the direction of the wave. So, sound waves are longitudinal. Also, it cannot travel through a vacuum and requires a medium (solid, liquid, or gas) to travel. Thus, a sound wave is called a mechanical wave.

Sound waves are mechanical waves because they need a material medium for propagation, like air or liquids like water or metals like silver.
